“Technical writing is any written form of writing or drafting technical communication used in a variety of technical and occupational fields, such as computer hardware and software, engineering, chemistry, aeronautics, robotics, finance, consumer electronics, and biotechnology,”
There is little room for being creative, which makes technical writing the opposite of creative writing. Technical writing has to be precise, exact and immediately to the point.
Assembly instructions, good ones anyway, are technical writing. Recipes are technical writing. Both tell a person how to do something step by step.

In the science trades, like chemistry, being vague and letting the reader make guesses can be fatal. Technical writing requires an exact command of language. Most technical writers are native speakers of the language they write in. Instructions in other countries clearly show the problem of trying to be a technical writer in a second language.
wikiHow is the Internet’s biggest source of technical writing.
